So please confirm, do your car Tail lights come on? if not check you car fuses.
BTW, does your number plate light work? The number plate light runs off the same circuit as well. It typically runs off the same circuit (wire) that feeds power to the Tail light(s).
The side light +ve should have power when you turn on your lights. when the original wires were crushed, they caused a short circuit that blew a fuse somewhere further up (perhaps in the vehicle wiring). as I understand it LEDs are polarity sensitive. If polarity is reversed the LED will not work. you have the +ve and -ve wires crossed over. So if the side lights are not working two things come to mind.ġ. If you replaced this wire all the way to the T connector then we can assume the wires are ok and not broken. Side lights & the left light wire had actually been done up in the mud guard bolt & all the wires crushed, the earth & power light on the were burned Sorry just finished my break at work so will continue when I get home.
#Right rear light housing connector not working full
Go to the side lights & the left light wire had actually been done up in the mud guard bolt & all the wires crushed, the earth & power light on the were burned or corroded as when I cut it off to have a look the wires were rusty so I did a full new 7.5amp wire from the to the T connection. The left rear side was still sealed with the blinker working, the brake working but no light when the headlights were on.ĭid the same wiring job as the right side. When I cut that light assembly off I checked the wiring & all 4 wires (red/green/yellow/white) all looked finr with no discolouration so I left the wiring there to the back of the trailer & individually rejoined the new.LED assembly with heat shrink solder connections & double heat shrink over the join. Thanks for the reply Zoran, so what happened was the original shity Dunbier rear right LED had broken its seal & the when I opened it the brake globes had corroded but the blinker was still working. In most simple wiring schemes, the -ve should be on all the time, and many trailer wiring issues are a result of a poor or missing earth at a light fitting - or a cross connected +ve. Have a read through this post - where I previously attached a trailer plug wiring diagram and some diagnostic tips.Īt the lights connections, bear in mind that each light should have two wires: a solid earth (-ve) connection and a positive (+ve) that only receives power when that light is activated - from a switch or brake pedal action.
If so, I suggest you undo your connections, plug the 7pin into the car and run a test to clearly identify all the wires coming out of each of the 2 connectors - ie which wire is the -ve and which are the +ve for the brakes, lights, side lights, blinkers etc. You made all your changes after these 2 connectors. Regarding where you made connections - am I understanding correctly that on your trailer you have a 7pin plug (that connects to the car) and that plug is connected to the T - connector - which splits into 2 connectors. there maybe other issues but as you need to start isolating the problem starting with whats coming out of your vehicle and working back to the lights. I find it difficult to follow what exactly is happening as at the start you say " I have stop & blinkers working fine but some reason have no tail lights" and then later you say " but the side lights, both blinker & tail/stop lights are not working".īut from what you describe it sounds like you have some cross connected wires. and the issues are where you have made your new connections OR at the light connections themselves BTW, was everything working before you rewired the trailer or were you fixing a specific problem?Īlso if everything was working previously then most probably the wiring up to where you made changes is ok.
